Signal generator

Abstract

Disclosed is a method of producing an output signal from a signal generator, comprising: determining a driving input to the signal generator, the driving input for driving the signal generator to provide a predetermined output signal, wherein the output signal includes at least one frame, the at least one frame comprising an active period and a dummy period and wherein the active period and dummy period are determined by the driving input. Also disclosed is a method of producing an output signal from a signal generator, comprising: receiving a synchronisation signal; obtaining an input signal for controlling the signal generator to generate an output signal comprising at least one frame wherein the at least one frame comprises at least one active period and at least one dummy period; producing the output signal comprising a series of frames; and, synchronising the output signal with the synchronisation signal by varying a duration of the at least one of the dummy period or active period.

Description

FIELD OF INVENTION[0001]This invention relates to a signal generator which is required to be synchronised with one or more other signal generators and / or radio wave receivers.BACKGROUND OF THE INVENTION[0002]A signal generator may generally be considered to a device which generates electronic signals and waveforms for various purposes and is well known in the art. Signal generators come in many different forms and can create repeating and non-repeating waveforms. Some signal generators may be referred to as a function generator which may be employed to generate more complex waveforms over a wide variety of wavelengths. Signal generators may include one or more voltage controlled oscillators, a direct digital synthesiser, DDS, or an arbitrary waveform generator, AWG. These and others which are applicable to this disclosure are well known in the art.[0003]The applications of signal generators vary tremendously. In one example application which is pertinent to the present disclosure, s...

AI Technical Summary

Benefits of technology

[0009]The method may further comprise: selecting a synchronisation point in the output signal; selecting a synchronisation point in the synchronisation signal; and, determining an offset error which relates to the difference between the two synchronisation points, wherein adjusting the duration of one or more active and dummy period reduces the offset error.

Problems solved by technology

In some applications, it may be necessary for signal jammers to operate in close proximity such that the signals issued from one jammer may interfere with the operation of another.
